HLS output to decklink SDI

[vmm2017]

I am new and trying to figure out how to output HLS stream to DeckLink card.

My command line is as follows:

gst-launch-1.0 souphttpsrc
location=http://devimages.apple.com/iphone/samples/bipbop/gear4/prog_index.m3u8
! hlsdemux ! decodebin name=u u. ! queue ! videoconvert ! videoscale !
decklinkvideosink mode=15 u. ! queue ! decklinkaudiosink

Output:
Setting pipeline to PAUSED ...
Pipeline is PREROLLING ...
WARNING: from element /GstPipeline:pipeline0/GstDecodeBin:u: Delayed linking
failed.
Additional debug info:
./grammar.y(506): gst_parse_no_more_pads ():
/GstPipeline:pipeline0/GstDecodeBin:u:
failed delayed linking some pad of GstDecodeBin named u to some pad of
GstQueue named queue1
ERROR: from element /GstPipeline:pipeline0/GstHLSDemux:hlsdemux0: GStreamer

Additional debug info:

/GstPipeline:pipeline0/GstHLSDemux:hlsdemux0:

Setting pipeline to NULL ...

Please guide me.
Thanks
Vick
